Ethisterone Powder – A Key Steroid Raw Material for Standardized Formulations and Hormone Product Development

Shaanxi Hongda Phytochemistry Co., Ltd. has an absolute advantage in the production and research and development of steroid hormone raw materials. Our norethindrone powder meets pharmaceutical-grade standards. Every batch of Ethisterone Powder API from Hongda has an absolute purity greater than 99.5% according to HPLC testing, with DHEA residue in the starting material less than 0.1%, and 17-beta spatial isomers reduced to undetectable levels (far exceeding the latest USP and EP pharmacopoeia's requirement of less than 0.1% for any single known impurity). We use chromatograms that fully comply with the ICH M7 toxicology red line, with clean peaks free of impurities, to help you easily pass official on-site audits by major European and American drug regulatory agencies. The 5mg norethindrone raw material provided by Shaanxi Hongda ranks among the top in purity in the market, and its quality has been widely recognized by customers.

Unique Advantages of Ethisterone Powder

1. Well-defined structure and strong stability: The ethinylprogesterone supplied by Shaanxi Hongda has a stable structure, suitable for further conversion and scale-up production of various steroid hormones.

2. Absolute purity of Norethindrone testosterone: Greater than 97.0% — 103.0% (perfectly replicates the latest EP11 / USP43 standards), 100% pure androgenetic adenosine progesterone, precisely and efficiently activating the human progesterone receptor (PR).

3. Known impurity DHEA residue (HPLC): Less than 0.1%, eliminating the potential risk of residual precursor hormones, preventing androgen-like side effects, and 100% compliant with European and American pharmaceutical regulatory approvals.
